Description

電泳顯示裝置及其製造方法Electrophoretic display device and method of manufacturing same

本發明係關於一種電泳顯示裝置,特別是一種可提高產率與可靠性並降低成本的電泳顯示裝置及其製造方法。The present invention relates to an electrophoretic display device, and more particularly to an electrophoretic display device and a method of fabricating the same that can improve yield and reliability and reduce cost.

電泳顯示裝置通常是一種可透過電泳來顯示影像之裝置,其中可透過外界形成之電場移動彩色電荷顆粒。此處,術語〞電泳〞是指當電場施加於其中具有擴散的電荷粒子之電泳擴散液(電泳墨水)時,透過庫侖力使電荷粒子發生運動之現象。An electrophoretic display device is generally a device that can display an image by electrophoresis, in which a color charge particle can be moved by an electric field formed by the outside. Here, the term "electrophoresis" refers to a phenomenon in which an electric field is caused to move by a Coulomb force when an electric field is applied to an electrophoretic diffusion liquid (electrophoretic ink) having diffused charge particles therein.

這種電泳顯示裝置使用了一種電泳技術,這種電泳技術即使在所施加之電壓發生偏移時也能以較長的時間顯示原始的影像。換言之,這種電泳裝置可在較長的時間內維持指定的畫面,而不必不斷地施加電壓。因此,可用這種電泳顯示裝置作為無須快速更換畫面之電子書。This electrophoretic display device uses an electrophoresis technique that can display an original image for a longer period of time even when the applied voltage is shifted. In other words, such an electrophoretic device can maintain a specified picture for a longer period of time without constantly applying a voltage. Therefore, such an electrophoretic display device can be used as an electronic book that does not require a quick change of pictures.

此外,這種電子顯示裝置並不倚賴於視角並可顯示出像紙一般適於觀看的影像,而這正是它與液晶顯示裝置的不同之處。因此,由於具有可彎曲、低能耗而不損害環境的性質,所以對於這種電泳顯示裝置的需求正在增大。Moreover, such an electronic display device does not rely on a viewing angle and can display an image that is generally suitable for viewing like paper, which is the difference between it and a liquid crystal display device. Therefore, the demand for such an electrophoretic display device is increasing due to the property of being bendable, low in energy consumption, and not damaging the environment.

而根據電泳層(或電泳膜)的結構,可將電泳顯示裝置劃分為微膠囊型電泳顯示裝置與微杯型電泳顯示裝置。According to the structure of the electrophoretic layer (or electrophoresis film), the electrophoretic display device can be divided into a microcapsule type electrophoretic display device and a microcup type electrophoretic display device.

「第1圖」為習知的微膠囊型電泳顯示裝置之結構的剖面圖。如「第1圖」所示,這種微膠囊型電泳顯示裝置,包含有相互接合的下層基板10與上層基板20;以及位於下層基板10與上層基板20間之電泳層30。Fig. 1 is a cross-sectional view showing the structure of a conventional microcapsule type electrophoretic display device. As shown in FIG. 1, the microcapsule-type electrophoretic display device includes an underlying substrate 10 and an upper substrate 20 bonded to each other, and an electrophoretic layer 30 between the lower substrate 10 and the upper substrate 20.

其中,此電泳層30包含有:第一黏結層34,係由一種透明材料形成;第二黏結層36;共同電極38,係由位於第一黏結層34與第二黏結層36之間;以及複數個微膠囊32,具有電荷粒子與電泳擴散液。雖然「第1圖」並未示出,但是,此下層基板包含有:與共同電極38相對的複數個畫素電極;複數個薄膜電晶體(TFT,thin film transistors),係用於作為向這些畫素電極施加電泳的開關裝置。The electrophoretic layer 30 includes: a first bonding layer 34 formed of a transparent material; a second bonding layer 36; and a common electrode 38 disposed between the first bonding layer 34 and the second bonding layer 36; A plurality of microcapsules 32 having charged particles and an electrophoretic diffusion liquid. Although not shown in FIG. 1, the lower substrate includes a plurality of pixel electrodes opposed to the common electrode 38; and a plurality of thin film transistors (TFT) are used as these. A switching device for applying electrophoresis to the pixel electrode.

此處,微膠囊32包含有:介電溶液、正粒子(+)與負粒子(-)。其中,配設於微膠囊32中之電荷粒子可在介電溶液中發生移動,藉以顯示影像。Here, the microcapsule 32 includes a dielectric solution, positive particles (+) and negative particles (-). The charged particles disposed in the microcapsules 32 can be moved in the dielectric solution to display an image.

在「第1圖」所示之電泳顯示裝置中,可分別製造出下層基板10、上層基板20與電泳層30。而後,可將電泳層30放置於下層基板10與上層基板20之間。In the electrophoretic display device shown in "Fig. 1", the lower substrate 10, the upper substrate 20, and the electrophoretic layer 30 can be separately manufactured. Then, the electrophoretic layer 30 can be placed between the lower substrate 10 and the upper substrate 20.

此處,可透過第二黏結層36使電泳層30連接於上層基板20,並透過第一黏結層34連接一塊隔離膜。其中,可將此隔離膜事先層疊第一黏結層於34之上,或者取消此隔離膜的設置。而後,可透過第一黏結層34使電泳層30連接於下層基板10。Here, the electrophoretic layer 30 can be connected to the upper substrate 20 through the second bonding layer 36, and a spacer film can be connected through the first bonding layer 34. Wherein, the separator may be laminated on the first adhesive layer 34 or the arrangement of the separator may be cancelled. Then, the electrophoretic layer 30 can be connected to the underlying substrate 10 through the first bonding layer 34.

如上所述,由於必須分別形成下層基板10、上層基板20及電泳層30,所以這種電泳顯示裝置之製造過程非常複雜。因此,這種電泳顯示裝置的製造方法需要耗費較長的時間並具有產率較低的缺點。同時,還會具有增大電泳膜30之製造成本的缺陷。As described above, since the lower substrate 10, the upper substrate 20, and the electrophoretic layer 30 must be separately formed, the manufacturing process of such an electrophoretic display device is very complicated. Therefore, the manufacturing method of such an electrophoretic display device requires a long time and has a disadvantage of low yield. At the same time, there is a drawback that the manufacturing cost of the electrophoretic film 30 is increased.

「第2圖」為習知的微杯型電泳顯示裝置之結構的剖面圖。如「第2圖」所示,這種微杯型電泳顯示裝置包含有:上層基板40;下層基板50;及內置於下層基板50上的電泳層。Fig. 2 is a cross-sectional view showing the structure of a conventional microcup type electrophoretic display device. As shown in FIG. 2, the microcup type electrophoretic display device includes an upper substrate 40, a lower substrate 50, and an electrophoretic layer built in the lower substrate 50.

此處,上層基板40包含有:基板42(或基底膜),係由透明材料形成;以及共同電極44,係由透明導電材料,如:氧化铟锡(ITO,Indium Tin Oxide)或氧化锌铟(IZO,Indium Zinc Oxide)形成。Here, the upper substrate 40 includes: a substrate 42 (or a base film) formed of a transparent material; and a common electrode 44 made of a transparent conductive material such as indium tin oxide (ITO) or zinc indium oxide. (IZO, Indium Zinc Oxide) formed.

而下層基板50包含有:基板52,係由透明或半透明材料形成;以及複數個畫素電極54,係配設於基板52上並朝向共同電極44。此處,可於基板52上形成作為開關裝置的複數個薄膜電晶體(圖中未示出),藉以向這些畫素電極54施加電壓。The lower substrate 50 includes a substrate 52 formed of a transparent or translucent material, and a plurality of pixel electrodes 54 disposed on the substrate 52 and facing the common electrode 44. Here, a plurality of thin film transistors (not shown) as switching means may be formed on the substrate 52 to apply voltages to the pixel electrodes 54.

其中,此電泳層包含:多個分隔壁56,係用於對形成於下層基板50上之子畫素進行定義,藉以顯示影像;以及電泳擴散液62(或電泳墨水),這些電泳擴散液被注入到子畫素中。此處,這些電泳擴散液62包含有:介電溶液以及複數個電荷粒子64。其中,在此介電溶液內這些電荷粒子64可沿著透過共用電極44與畫素電極54所形成之電場進行移動。The electrophoretic layer includes: a plurality of partition walls 56 for defining sub-pixels formed on the lower substrate 50 to display images; and an electrophoretic diffusion liquid 62 (or electrophoretic ink), which are injected into the electrophoretic diffusion liquid. In the sub-picture. Here, these electrophoretic diffusion liquids 62 include a dielectric solution and a plurality of charged particles 64. The charge particles 64 in the dielectric solution are movable along an electric field formed by the common electrode 44 and the pixel electrode 54.

在具有上述結構之微杯型電泳顯示裝置中,可將電泳擴散液62注入透過形成於下層基板50上之分隔壁56所定義之子畫素中。換言之,此電泳擴散液62可內置於下層基板50中。In the microcup type electrophoretic display device having the above structure, the electrophoretic diffusion liquid 62 can be injected into the subpixel defined by the partition wall 56 formed on the lower substrate 50. In other words, the electrophoretic diffusion liquid 62 can be built in the lower substrate 50.

此處,當此分隔壁56由無機材料形成時,「第3圖」所示置電泳擴散液62之填入過程中無法注滿電泳擴散液並會產生氣泡。Here, when the partition wall 56 is formed of an inorganic material, the electrophoretic diffusion liquid 62 cannot be filled with the electrophoretic diffusion liquid and bubbles are generated during the filling process of the electrophoretic diffusion liquid 62 as shown in "Fig. 3".

而這種電泳顯示裝置具有位於形成在下層基板50上之顯示區域的外側區中之密封劑以及用於時上層基板40與下層基板50相接合之密封劑。但是,卻並未形成用於防止使溢出之密封劑流向密封劑塗敷區域內外兩側的導件。Further, such an electrophoretic display device has a sealant located in an outer region of a display region formed on the lower substrate 50, and a sealant for bonding the upper substrate 40 and the lower substrate 50. However, a guide for preventing the overflow of the sealant from flowing to the outside and the outside of the sealant application region has not been formed.

因此,用於使上層基板40與下層基板50相接合之密封劑可向「第4圖」所示之顯示面板內、外側溢出,進而可造成作業失誤。同時,若這種密封劑向顯示面板內、外側溢出,則無法順利而成功地對上層基板40與下層基板50進行接合製程。Therefore, the sealant for joining the upper substrate 40 and the lower substrate 50 can overflow into the inside and the outside of the display panel shown in FIG. 4, and the operation error can be caused. At the same time, if such a sealant overflows into the inside and the outside of the display panel, the bonding process of the upper substrate 40 and the lower substrate 50 cannot be smoothly and successfully performed.

此外,密封劑之溢出會使顯示面板無法相對於外界的包圍無法完整,並可能使此電泳顯示裝置受到外界空氣與水份的污染。因此,由於上層基板與下層基板相互接合之密封劑的溢出所形成的缺陷可降低電泳顯示裝置之產率與可靠性。In addition, the overflow of the sealant may make the display panel unable to be completely enclosed with respect to the outside, and may cause the electrophoretic display device to be contaminated by outside air and moisture. Therefore, the defects formed by the overflow of the sealant bonded to the upper substrate and the lower substrate can reduce the yield and reliability of the electrophoretic display device.

因此,本發明提供了一種電泳顯示裝置及其製造方法。Accordingly, the present invention provides an electrophoretic display device and a method of fabricating the same.

在本發明實施例之電泳顯示裝置100中,可透過電荷粒子132填充這些子畫素,並透過向共同電極114與這些畫素電極124所施加之電壓在介電溶液中使位於子畫素內之電荷粒子132產生運動,藉以產生單色影像與彩色影像。其中,此上層基板110包含有:第一基板112(或基底膜),係由透明玻璃或塑料形成;共同電極114,係形成於此第一基板112上;以及密封層116,係用於將電泳擴散液130內置於上層基板110上並用於使上層基板110與下層基板120相互連接。In the electrophoretic display device 100 of the embodiment of the present invention, the sub-pixels are filled by the charge particles 132, and the voltage applied to the common electrode 114 and the pixel electrodes 124 is placed in the sub-pixel in the dielectric solution. The charged particles 132 generate motion to produce a monochrome image and a color image. The upper substrate 110 includes: a first substrate 112 (or a base film) formed of transparent glass or plastic; a common electrode 114 formed on the first substrate 112; and a sealing layer 116 for The electrophoretic diffusion liquid 130 is built in the upper substrate 110 and is used to connect the upper substrate 110 and the lower substrate 120 to each other.

此處,組成上層基板110之第一基板112、共同電極114與密封層116必須是透明的,藉以顯示影像。因此,可透過柔性透明材料形成第一基板112,並透過如:氧化铟锡(ITO,Indium Tin Oxide)或氧化锌铟(IZO,Indium Zinc Oxide)之透明導電材料形成共同電極114。其中,可於上層基板110之共同電極114上且對應於子畫素所顯示之影像的預定區域上形成密封層116。Here, the first substrate 112, the common electrode 114, and the sealing layer 116 constituting the upper substrate 110 must be transparent to display an image. Therefore, the first substrate 112 can be formed through the flexible transparent material, and the common electrode 114 can be formed through a transparent conductive material such as Indium Tin Oxide (ITO) or Indium Zinc Oxide (IZO). The sealing layer 116 may be formed on the common electrode 114 of the upper substrate 110 and on a predetermined region corresponding to the image displayed by the sub-pixel.

此處,密封層116係用於密封電泳擴散液130。其中,可將透明材料塗敷於上層基板110之共同電極114上,並透過光微刻製程對與子畫素相應的所塗敷之材料進行圖案化處理,藉以形成密封層116。或者,還可用具有壓紋雕刻圖案之捲軸透過捲軸式(Roll-to-Roll)製程形成密封層116。此處,用於在上層基板110上形成密封層116之材料可與用於形成下文即將描述之分隔壁126之材料相同或是不同。Here, the sealing layer 116 is used to seal the electrophoretic diffusion liquid 130. The transparent material may be applied to the common electrode 114 of the upper substrate 110, and the coated material corresponding to the sub-pixels may be patterned by a light micro-etching process to form the sealing layer 116. Alternatively, the sealing layer 116 may be formed by a roll-to-roll process using a reel having an embossed engraving pattern. Here, the material for forming the sealing layer 116 on the upper substrate 110 may be the same as or different from the material for forming the partition wall 126 to be described later.

此處,下層基板120包含有:第二基板122(或基底膜)、畫素電極124、分隔壁126、電泳擴散液130及夾層128。同時,可於第二基板122上形成複數個閘極線(圖中未示出)與複數個資料線(圖中未示出),並分別於這些資料線與閘極線之交叉點上形成薄膜電晶體(圖中未示出)。進而,可將電泳擴散液130注入透過內置於下層基板120中之分隔壁126所定義之子畫素中。Here, the lower substrate 120 includes a second substrate 122 (or a base film), a pixel electrode 124, a partition wall 126, an electrophoretic diffusion liquid 130, and an interlayer 128. At the same time, a plurality of gate lines (not shown) and a plurality of data lines (not shown) may be formed on the second substrate 122, and respectively formed at intersections of the data lines and the gate lines. Thin film transistor (not shown). Further, the electrophoretic diffusion liquid 130 can be injected into the sub-pixel defined by the partition wall 126 built in the lower substrate 120.

其中,刻透過透明玻璃基板、具有柔性的塑料基板或金屬基板形成此第二基板122。同時,由於第二基板122位於顯示影像之屏幕對對側,所以第二基板此122不必是透明的。The second substrate 122 is formed by a transparent glass substrate, a flexible plastic substrate or a metal substrate. At the same time, since the second substrate 122 is located on the opposite side of the screen on which the image is displayed, the second substrate 122 does not have to be transparent.

此處,刻透過具有較低電阻值的銀(Ag)、鋁(Al)或銀-鋁合金形成具有單層結構的每條閘極線與每條資料線。或者,可包含有單層與透過具有優異導電特性之鉻(Cr)、鈦(Ti)或鉭(Ta)所形成之另一層的多層結構之閘極線與資料線。Here, each of the gate lines and each of the data lines having a single layer structure is formed by silver (Ag), aluminum (Al) or silver-aluminum alloy having a lower resistance value. Alternatively, a gate line and a data line of a multilayer structure having a single layer and another layer formed by passing chromium (Cr), titanium (Ti) or tantalum (Ta) having excellent conductive properties may be included.

此外,還可透過位於此閘極線與資料線間之氮化層形成閘極絕緣膜。同時,可在閘極線與資料線間之每一交叉點上形成薄膜電晶體。此處,這些薄膜電晶體之閘極可連接於閘極線,而此薄膜電晶體之源極係連接於資料線。同時,此薄膜電晶體之汲極可連接於畫素電極124。In addition, a gate insulating film may be formed through a nitride layer between the gate line and the data line. At the same time, a thin film transistor can be formed at each intersection between the gate line and the data line. Here, the gate of the thin film transistors can be connected to the gate line, and the source of the thin film transistor is connected to the data line. At the same time, the drain of the thin film transistor can be connected to the pixel electrode 124.

此處,這些畫素電極124可對應於透過分隔壁126所定義之複數個子畫素。進而,畫素電極124可透過薄膜電晶體之開關作業將電壓施加於子畫素。同時,這些畫素電極124可分別透過接觸孔與薄膜電晶體之汲極進行電性連接。其中,可透過例如,銅、鋁及氧化铟锡等材料形成這些畫素電極124。或者,這種畫素電極還可以是由位於銅、鋁或氧化铟锡所形成之層上的鎳層和/或金層所形成之多層結構。Here, the pixel electrodes 124 may correspond to a plurality of sub-pixels defined by the partition wall 126. Further, the pixel electrode 124 can apply a voltage to the sub-pixel by a switching operation of the thin film transistor. At the same time, the pixel electrodes 124 can be electrically connected to the drains of the thin film transistor through the contact holes. Among them, these pixel electrodes 124 can be formed by, for example, materials such as copper, aluminum, and indium tin oxide. Alternatively, the pixel electrode may be a multilayer structure formed of a nickel layer and/or a gold layer on a layer formed of copper, aluminum or indium tin oxide.

進而,可於下層基板120上形成分隔壁126,藉以定義出複數個子畫素。其中,可使此分隔壁126環繞畫素電極124,藉以對子畫素進行定義。此處,可透過與內置於子畫素中之電泳擴散液130具有相同物理特性之非極性有機材料形成此分隔壁126。例如,此分隔壁126與電泳擴散液130可包含有沒有極性的介電溶液。同時,可透過光微刻技術或模製印刷技術形成高度為1微米~100微米的分隔壁126。如上所述,可使形成於下層基板120上之分隔壁126具有相鄰的獨立結構。Further, a partition wall 126 may be formed on the lower substrate 120 to define a plurality of sub-pixels. Wherein, the partition wall 126 can surround the pixel electrode 124 to define the sub-pixel. Here, the partition wall 126 can be formed by a non-polar organic material having the same physical properties as the electrophoretic diffusion liquid 130 built in the sub-pixel. For example, the partition wall 126 and the electrophoretic diffusion liquid 130 may contain a dielectric solution having no polarity. At the same time, the partition wall 126 having a height of 1 μm to 100 μm can be formed by a photo-inscription technique or a molding printing technique. As described above, the partition walls 126 formed on the lower substrate 120 can have adjacent independent structures.

進而,可將包含有複數個電荷粒子132及介電溶液之電泳擴散液130注入導透過分隔壁126所定義之子畫素中。換言之,可使此電泳擴散液130內置於下層基板120中。此處,可透過狹縫塗佈法、鑄造法、捲軸塗佈法、點膠法、擠壓法、網版印刷法、噴塗法或光微刻法在填充了電泳擴散液130之下層基板120上形成子畫素。Further, the electrophoretic diffusion liquid 130 including the plurality of charged particles 132 and the dielectric solution may be injected into the sub-pixel defined by the partition wall 126. In other words, the electrophoretic diffusion liquid 130 can be built in the lower substrate 120. Here, the underlying substrate 120 may be filled with the electrophoretic diffusion liquid 130 by a slit coating method, a casting method, a roll coating method, a dispensing method, an extrusion method, a screen printing method, a spray method, or a light micro-engraving method. Form a sub-pixel on it.

其中,此電泳擴散液130可包含:不具極性之介電溶液;以及透過正極(+)或負極(-)進行充電之複數個電荷粒子132。換言之,可透過充電使電荷粒子132之一部分具有正極性(+),並使其他電荷粒子132具有負極性(-)。可透過紅色、綠色、黃色、青色、洋紅、黑色與白色中的至少一種顏色對電荷粒子132進行染色。The electrophoretic diffusion liquid 130 may include: a dielectric solution having no polarity; and a plurality of charged particles 132 charged through the positive electrode (+) or the negative electrode (−). In other words, one portion of the charge particles 132 has a positive polarity (+) and the other charge particles 132 have a negative polarity (-) by charging. The charge particles 132 may be dyed by at least one of red, green, yellow, cyan, magenta, black, and white.

此處,若圍繞電泳擴散液130之外壁與經過處理之電泳擴散液130具有不同的物理特性,則意味著未完全注入此電泳擴散液130。因此,這種未完全填充狀況會發生並因填充過程中所產生之氣泡產生缺陷。Here, if the outer wall surrounding the electrophoretic diffusion liquid 130 has different physical properties from the treated electrophoretic diffusion liquid 130, it means that the electrophoretic diffusion liquid 130 is not completely injected. Therefore, this incomplete filling condition occurs and defects are generated due to bubbles generated during the filling process.

如上所述,本發明實施例之電泳顯示裝置所包含之電泳擴散液130的有機材料之物理特性與圍繞着內置於下層基板120中之電泳擴散液130的外壁,即分隔壁126有機材料之物理特性相同。例如,此分隔壁126與介電容液可以是沒有極性的。As described above, the physical properties of the organic material of the electrophoretic diffusion liquid 130 included in the electrophoretic display device of the embodiment of the present invention and the outer wall surrounding the electrophoretic diffusion liquid 130 built in the lower substrate 120, that is, the physical properties of the partition wall 126 organic material. The same characteristics. For example, the dividing wall 126 and the dielectric fluid may be non-polar.

因此,可順利地進行於下層基板120上內置電泳擴散液130的製程,同時防止在上層基板110與下層基板120間之接合過程中產生故障。Therefore, the process of embedding the electrophoretic diffusion liquid 130 on the lower substrate 120 can be smoothly performed while preventing a failure in the bonding process between the upper substrate 110 and the lower substrate 120.

此外,由於此電泳擴散液130被內置於下層基板120上,所以可提高此電泳顯示裝置之驅動穩定性。Further, since the electrophoretic diffusion liquid 130 is built in the lower substrate 120, the driving stability of the electrophoretic display device can be improved.

此外,由於可透過多種顏色對電荷粒子132進行染色,所以可顯示多種色彩影像,進而還可提高這種電泳顯示裝置之顯示品質。In addition, since the charge particles 132 can be dyed through a plurality of colors, a plurality of color images can be displayed, and the display quality of the electrophoretic display device can be improved.

此處,若電荷粒子132直接與密封層116相接觸,則會在原始配設產生故障或使電化特性產生故障。換言之,在這種狀況中即使向子畫素施加電場,也無法使電荷粒子132發生移動並會產生圖像顯示失敗的錯誤。因此,為了防止此電荷粒子132直接與密封層116發生接觸,可形成對應於上層基板110上之密封層116的夾層128。此處,密封層116與夾層128具有非極化特性。Here, if the charge particles 132 are directly in contact with the sealing layer 116, a failure occurs in the original arrangement or a malfunction occurs in the electrochemical characteristics. In other words, even if an electric field is applied to the sub-pixels in such a situation, the charge particles 132 cannot be moved and an error in image display failure may occur. Therefore, in order to prevent the charged particles 132 from coming into direct contact with the sealing layer 116, the interlayer 128 corresponding to the sealing layer 116 on the upper substrate 110 may be formed. Here, the sealing layer 116 and the interlayer 128 have non-polarization characteristics.

因此,可於分隔壁126上形成夾層128,並透過電泳擴散液130對子畫素進行填充。此處,可將透過厚度為若干奈米之絕緣有機材料所形成之薄膜作為夾層128。例如,可透過丁酮(MEK,Methyl Ethyl Ketone)形成夾層128。同時,還可在夾層128中加入淺黃色,藉以提高對比度。Therefore, the interlayer 128 can be formed on the partition wall 126, and the sub-pixels can be filled by the electrophoretic diffusion liquid 130. Here, a film formed by an insulating organic material having a thickness of several nanometers may be used as the interlayer 128. For example, the interlayer 128 can be formed by methyl ethyl ketone (MEK, Methyl Ethyl Ketone). At the same time, a light yellow color can also be added to the interlayer 128 to increase the contrast.

為了形成此夾層128,可透過如丁酮之透明材料對分隔壁126進行塗覆,並透過電泳擴散液130對子畫素進行填充。而後,可對所塗覆之透明材料執行刻印製程或光刻製程,進而形成夾層128。或者,還可用具有壓紋雕刻圖案之捲軸透過捲軸式(Roll-to-Roll)製程形成此夾層128。In order to form the interlayer 128, the partition wall 126 may be coated with a transparent material such as methyl ethyl ketone, and the sub-pixels may be filled by the electrophoretic diffusion liquid 130. An imprinting process or a photolithography process can then be performed on the coated transparent material to form the interlayer 128. Alternatively, the interlayer 128 may be formed by a roll-to-roll process using a reel having an embossed engraving pattern.

在本發明實施例中,可於下層基板120上形成夾層128。而在本發明另一實施例中,可透過此夾層128防止電荷粒子132與密封層116進行直接接觸。同時,在形成此夾層128之處,不存在對基板(上層基板110或下層基板120)之限製。In the embodiment of the present invention, the interlayer 128 may be formed on the lower substrate 120. In another embodiment of the invention, the charge particles 132 are prevented from coming into direct contact with the sealing layer 116 through the interlayer 128. Meanwhile, at the point where the interlayer 128 is formed, there is no limitation on the substrate (the upper substrate 110 or the lower substrate 120).

在具有上述結構的本發明實施例之電泳顯示裝置100中,可透過上層基板110的密封層116使上層基板110與下層基板120相接合。因此,這種電泳顯示裝置可防止因用於使上層基板與下層基板相互接合之密封劑溢出所產生的缺陷。In the electrophoretic display device 100 of the embodiment of the present invention having the above configuration, the upper substrate 110 and the lower substrate 120 can be bonded through the sealing layer 116 of the upper substrate 110. Therefore, such an electrophoretic display device can prevent defects caused by overflow of a sealant for bonding the upper substrate and the lower substrate to each other.

同時,在本發明實施例中,可透過完全密封的顯示面板防止外界空氣與水分元素對此電泳顯示裝置造成污染。因此,可提高這種電泳顯示裝置之產率與可靠性。In the meantime, in the embodiment of the present invention, the external air and moisture elements can be prevented from contaminating the electrophoretic display device through the completely sealed display panel. Therefore, the yield and reliability of such an electrophoretic display device can be improved.

下面,將結合「第6a圖」至「第8圖」對本發明實施例之電泳顯示裝置之製造方法進行描述。Hereinafter, a method of manufacturing an electrophoretic display device according to an embodiment of the present invention will be described with reference to "Fig. 6a" to "Fig. 8".

「第6a圖」至「第6c圖」示出了本發明實施例中電泳顯示裝置之上層基板的製造方法。"Fig. 6a" to "Fig. 6c" show a method of manufacturing the upper substrate of the electrophoretic display device in the embodiment of the present invention.

如「第6a圖」所示,可在透過透明玻璃或柔性透明塑料所形成之第一基板112(或基底膜)上用如氧化铟锡(ITO,Indium Tin Oxide)或氧化锌铟(IZO,Indium Zinc Oxide)之類的導電材料形成共同電極114。As shown in Fig. 6a, for example, indium tin oxide (ITO) or indium zinc oxide (IZO) may be used on the first substrate 112 (or base film) formed by transparent glass or flexible transparent plastic. A conductive material such as Indium Zinc Oxide) forms a common electrode 114.

如「第6b圖」所示,進而可透過透明材料115對第一基板112進行塗覆,藉以覆蓋共同電極114。As shown in "Fig. 6b", the first substrate 112 can be coated with a transparent material 115 to cover the common electrode 114.

而後,如「第6c圖」所示,可透過刻印製程或光刻製程對塗覆於第一基板112上之透明材料115進行圖案化處理,進而形成密封層116。此時,密封層116係對應於用以顯示影像之子畫素。Then, as shown in FIG. 6c, the transparent material 115 coated on the first substrate 112 can be patterned by an imprint process or a photolithography process to form the sealing layer 116. At this time, the sealing layer 116 corresponds to a sub-pixel for displaying an image.

此處,用於在上層基板110上形成密封層116之透明材料與用於形成在下文將要進行描述之分隔壁126之材料可以是相同的或是不同的。或者,還可用具有壓紋雕刻圖案之捲軸透過捲軸式(Roll-to-Roll)製程形成此密封層116。此處,密封層116與分隔壁126可具有非極性。Here, the transparent material for forming the sealing layer 116 on the upper substrate 110 may be the same as or different from the material for forming the partition wall 126 which will be described later. Alternatively, the sealing layer 116 may be formed by a roll-to-roll process using a reel having an embossed engraving pattern. Here, the sealing layer 116 and the partition wall 126 may have a non-polarity.

以上,結合「第6a圖」至「第6c圖」對本發明實施例之電泳顯示裝置之上層基板110的製造方法進行了描述。The method of manufacturing the upper substrate 110 of the electrophoretic display device according to the embodiment of the present invention has been described above with reference to "6a to 6c".

「第7a圖」至「第7d圖」為本發明實施例之電泳顯示裝置之下層基板的製造方法。其中,「第6a圖」至「第6c圖」所描述之上層基板110之製程所需的時間與「第7a圖」至「第7d圖」中所描述之下層基板120之製程所需的時間相同,因此可順利且高效地執行上層基板110與下層基板120之接合製程。"7a" to "7d" are manufacturing methods of the underlying substrate of the electrophoretic display device according to the embodiment of the present invention. The time required for the process of the upper substrate 110 described in "Fig. 6a" to "Fig. 6c" and the time required for the process of the lower substrate 120 described in "Fig. 7a" to "Fig. 7d" The same, the bonding process of the upper substrate 110 and the lower substrate 120 can be performed smoothly and efficiently.

首先,如「第7a圖」所示,可於具有與複數個子畫素相對應之薄膜電晶體的第二基板122(或基底膜)上塗覆銅、鋁或氧化铟锡。而後,可透過光刻法對所塗覆之銅、鋁或氧化铟锡進行圖案化處理,進而形成複數個畫素電極124。同時,可使這些畫素電極124分別與複數個子畫素相對應。此處,為了形成這些畫素電極124,可進一步在銅層、鋁層或氧化铟锡層上形成鎳層和/或金層,藉以構成多層結構。進而,可透過下列製程製造出透過分隔壁126進行定義之複數個子畫素。First, as shown in "Fig. 7a", copper, aluminum or indium tin oxide may be coated on the second substrate 122 (or base film) having a thin film transistor corresponding to a plurality of sub-pixels. Then, the applied copper, aluminum or indium tin oxide can be patterned by photolithography to form a plurality of pixel electrodes 124. At the same time, these pixel electrodes 124 can be respectively associated with a plurality of sub-pixels. Here, in order to form these pixel electrodes 124, a nickel layer and/or a gold layer may be further formed on the copper layer, the aluminum layer or the indium tin oxide layer, thereby constituting a multilayer structure. Further, a plurality of sub-pixels defined by the partition wall 126 can be manufactured through the following processes.

如「第7b圖」所示,可於其上形成有畫素電極124之第二基板122上塗覆有機材料。而後,可對這些有機材料進行圖案化處理,藉以形成分隔壁126。進而,可透過分隔壁126定義出將用電泳擴散液130進行填充的子畫素。As shown in "Fig. 7b", the organic material may be coated on the second substrate 122 on which the pixel electrode 124 is formed. These organic materials can then be patterned to form a dividing wall 126. Further, sub-pixels to be filled with the electrophoretic diffusion liquid 130 can be defined by the partition wall 126.

進而,可透過光微刻技術或模製印刷技術形成高度為1微米~100微米的分隔壁126。此處,分隔壁126可於將填充子畫素之電泳擴散液130進行接觸。因此,用於形成分隔壁126之有機材料可與電泳擴散液130包含之介電容液所具有相同的物理特性。例如,分隔壁126與此介電容液可以都是非極性的。Further, the partition wall 126 having a height of 1 μm to 100 μm can be formed by a photolithography technique or a mold printing technique. Here, the partition wall 126 may be in contact with the electrophoretic diffusion liquid 130 filling the sub-pixels. Therefore, the organic material used to form the partition wall 126 can have the same physical properties as the dielectric fluid contained in the electrophoretic diffusion liquid 130. For example, the partition wall 126 and the dielectric fluid may both be non-polar.

如「第7c圖」所示,可將具有透過正極(+)或負極(-)進行充電之電荷粒子132的電泳擴散液130注入到透過分隔壁126所定義之子畫素中。因此,可於下層基板120上內置電泳擴散液130。此處,可透過狹縫塗佈法、鑄造法、捲軸塗佈法、點膠法、擠壓法、網版印刷法、噴塗法或光微刻法在填充了電泳擴散液130之下層基板120上形成子畫素。As shown in "Fig. 7c", the electrophoretic diffusion liquid 130 having the charged particles 132 charged through the positive electrode (+) or the negative electrode (-) can be injected into the sub-pixels defined by the partition wall 126. Therefore, the electrophoretic diffusion liquid 130 can be built in the lower substrate 120. Here, the underlying substrate 120 may be filled with the electrophoretic diffusion liquid 130 by a slit coating method, a casting method, a roll coating method, a dispensing method, an extrusion method, a screen printing method, a spray method, or a light micro-engraving method. Form a sub-pixel on it.

而後,如「第7d圖」所示,可於分隔壁126上形成夾層128,並透過電泳擴散液130對與上層基板110上之密封層116相對應的子畫素進行填充。例如,可透過丁酮形成此夾層128。Then, as shown in "Fig. 7d", the interlayer 128 can be formed on the partition wall 126, and the sub-pixel corresponding to the sealing layer 116 on the upper substrate 110 can be filled by the electrophoretic diffusion liquid 130. For example, the interlayer 128 can be formed by methyl ethyl ketone.

其中,此夾層128係用於防止電荷粒子132與上層基板110之密封層116發生接觸。具體而言,這種透明材料,例如:丁酮可塗覆於分隔壁126以及透過電泳擴散液130進行填充的子畫素上。而後,可對所塗覆之透明材料進行刻印製程或光刻製程,可透過刻印製程或光刻製程形成夾層128。或者,還可用具有壓紋雕刻圖案之捲軸透過捲軸式製程形成夾層128。The interlayer 128 is used to prevent the charged particles 132 from coming into contact with the sealing layer 116 of the upper substrate 110. Specifically, such a transparent material, for example, methyl ethyl ketone, may be applied to the partition wall 126 and the sub-pixels filled by the electrophoretic diffusion liquid 130. The coated transparent material can then be subjected to an engraving process or a photolithography process, and the interlayer 128 can be formed by an imprint process or a photolithography process. Alternatively, the interlayer 128 may be formed by a roll process having a embossed engraving pattern.

在本發明實施例中,可於下層基板120上形成夾層128。但這並不對本發明構成限制。在本發明實施例中,可於上層基板110上形成夾層128。換言之,可於任意一塊基板(即上層基板110或下層基板120)上形成此夾層128,因此這種結構可防止132直接與密封層116相互接觸。而當於上層基板110上形成夾層128時,可於「第6c圖」所示之密封層116上塗覆透明材料。而後,可透過刻印製程或光刻製程形成夾層128。In the embodiment of the present invention, the interlayer 128 may be formed on the lower substrate 120. However, this does not limit the invention. In the embodiment of the present invention, the interlayer 128 may be formed on the upper substrate 110. In other words, the interlayer 128 can be formed on any one of the substrates (i.e., the upper substrate 110 or the lower substrate 120), and thus the structure can prevent the 132 from directly contacting the sealing layer 116. When the interlayer 128 is formed on the upper substrate 110, a transparent material can be applied to the sealing layer 116 shown in "Fig. 6c". The interlayer 128 can then be formed by an imprint process or a photolithography process.

「第8圖」為用於使上層基板110與下層基板120相互接合之方法的示意圖。The "Fig. 8" is a schematic view of a method for joining the upper substrate 110 and the lower substrate 120 to each other.

如「第8圖」所示,可透過捲軸140執行之捲軸式製程使「第6a圖」至「第6c圖」所示之上層基板110與「第7a圖」至「第7d圖」所示之下層基板120相結合。此時,捲軸式製程之作業條件為向上層基板110與下層基板120施加預定壓力,同時可透過向上層基板110與下層基板120施加預定溫度而執行退火製程。As shown in Figure 8, the reel-type process performed by the reel 140 allows the upper substrate 110 and the "7a to" to 7d charts shown in "Fig. 6a" to "6c". The lower substrate 120 is combined. At this time, the working condition of the reel type process is that a predetermined pressure is applied to the upper substrate 110 and the lower substrate 120, and an annealing process can be performed by applying a predetermined temperature to the upper substrate 110 and the lower substrate 120.

在本發明實施例之電泳顯示裝置中,可按照上述方法使上層基板與下層基板相互接合。因此,可順利地實現上層基板與下層基板間之接合,藉以簡化整個製造過程。進而,提高生產率。In the electrophoretic display device of the embodiment of the invention, the upper substrate and the lower substrate can be bonded to each other in accordance with the above method. Therefore, the bonding between the upper substrate and the lower substrate can be smoothly achieved, thereby simplifying the entire manufacturing process. Further, productivity is improved.

此外,還可透過其它不使用密封劑之方法使本發明實施例之電泳顯示裝置的上層基板與下層基板相互結合。進而,減少接合制程中所產生之缺陷。In addition, the upper substrate and the lower substrate of the electrophoretic display device of the embodiment of the present invention can be combined with each other by other methods without using a sealant. Further, the defects generated in the bonding process are reduced.

因此,本發明可對顯示面板進行完全地密封,並防止因外部空氣及水分因素對此電泳顯示裝置產生污染。因此,可提高電泳顯示裝置的產率與可靠性。Therefore, the present invention can completely seal the display panel and prevent contamination of the electrophoretic display device due to external air and moisture factors. Therefore, the yield and reliability of the electrophoretic display device can be improved.

同時,在本發明實施例中,可將電泳擴散液內置於下層基板120上。因此,可減少電泳顯示裝置的製造成本。Meanwhile, in the embodiment of the present invention, the electrophoretic diffusion liquid may be built in the lower substrate 120. Therefore, the manufacturing cost of the electrophoretic display device can be reduced.

應用上述製造方法,可將電泳擴散液注入到由分隔壁、上層基板與下層基板所包圍之子畫素中。同時,由電泳擴散液所圍繞之外壁,即分隔壁係由有機材料形成。因此,此分隔壁之物理特性可與電泳擴散液所包含之介電容液之物理特性相同。具體而言,此分隔壁與電泳擴散液所包含之介電容液可皆具有非極性特徵。According to the above manufacturing method, the electrophoretic diffusion liquid can be injected into the sub-pixel surrounded by the partition wall, the upper substrate, and the lower substrate. At the same time, the outer wall surrounded by the electrophoretic diffusion liquid, that is, the partition wall is formed of an organic material. Therefore, the physical properties of the partition wall can be the same as those of the dielectric fluid contained in the electrophoretic diffusion liquid. Specifically, the partition wall and the dielectric fluid contained in the electrophoretic diffusion liquid may have non-polar characteristics.

因此,可使將電泳擴散液內置於下方基板上之過程更為順暢有效。此外,當使上層基板與下層基板相互接合時,可防止在子畫素中產生故障。Therefore, the process of embedding the electrophoretic diffusion liquid on the lower substrate can be made smoother and more efficient. Further, when the upper substrate and the lower substrate are bonded to each other, it is possible to prevent a malfunction in the sub-pixel.

進而,本發明實施例之電泳顯示裝置之製造方法具有可透過內部結構形成液晶顯示器的優點。Further, the method of manufacturing an electrophoretic display device according to an embodiment of the present invention has an advantage that a liquid crystal display can be formed through an internal structure.
